Reference to cases 7 and 9 as illustrating the possible spontaneous cure of traumatic aneurisms is of great interest. I saw a number of cases successfully treated by proximal ligature; also a number where continuous improvement followed rest, and which were sent home for further treatment. None of these demand any special mention. One case of a very special nature, which terminated fatally, is of great interest:-- (5) In a man wounded at Belmont the bullet entered the second left intercostal space and was retained in the thorax. He was sent directly to the Base and came under the care of Mr. Thornton at No. 1 General Hospital, Wynberg. Signs of wound of the lung developed in the form of haemoptysis and left haemothorax. The left radial pulse was almost imperceptible. The entry wound did not close by primary union, and three weeks later an incision was made into the chest in consequence of the presence of fever, progressive emaciation, and weakness. Breaking down blood clot was evacuated: general improvement followed, and the radial pulse increased considerably in volume. A fortnight later sudden severe haemorrhage occurred from the external wound, and the man rapidly collapsed and died. At the post-mortem a traumatic aneurism the size of an orange was found in connection with an oval wound in the first portion of the left subclavian artery which admitted the tip of the forefinger. This case is noteworthy as an illustration of the magnitude of an artery which can be wounded without leading to rapid death from primary haemorrhage, even when in communication with a serous sac, and still more as emphasising the importance of weakening of the radial pulse as a sign in connection with a wound of the upper part of the chest on the left side. It is somewhat surprising that this sign was not marked in two cases (Nos. 13 and 14, p. 140) recorded below, in which the innominate and right carotid arteries respectively were probably perforated. (6) _Traumatic popliteal aneurism._--Wounded at Modder River. _Entry_ (Mauser), over centre of tibia 1 inch above the tubercle. _Exit_, about centre of popliteal space. No haemorrhage of any importance occurred from the wound, but there was a typical haemarthrosis, which subsided slowly. Twelve days after the injury a pulsating swelling the size of a hen's egg, to which attention was drawn on account of pain, was noted in popliteal space. The pulsation extended upwards in the line of the artery some 3 inches. The limb was placed on a splint and treated by rest, and a month later the aneurism had decreased to one half its former size, the wall having greatly increased in firmness. Pulsation was easily controlled by pressure above the tumour; there was no thrill present, but a high-pitched bellows murmur. The patient was sent home on February 1.
